Information from the tracking, calorimetry and muon detection systems of the CMS detector at the Large Hadron Collider at CERN, can be combined to give a holistic description of a proton-proton collision in terms of photons, electrons, muons and hadrons. A 'particle flow' technique is presented which seeks to determine the energy and momenta of these particles. By decomposing events in this way we may expect superior efficiencies and energy resolution for jets, missing transverse energy and tau reconstruction compared to conventional reconstruction techniques used at hadron colliders. The application of particle flow to CMS testbeam data is presented.
